Their children John born 11 July 1868 in Cookstown.Sisters Margaret & Mary were born inNI and died in Glasgow sometime after visiting the New York Worlds Fair[1939. Ellen married a Scot surnamed McCann,she died abt 1957 in glasgow. Son Patrick about whom I knowonly that he diedin Glasgow abt 1955. There are some stories about 3 other brothers named Thomas,Edward and Charles. John arrived in NY (ELLIS ISLAND) 2 Sept 1893 on SS Paris out of Southampton.
